In this work a paleohistological approach to two sauropod dinosaurs, Galvesaurus herreroi Barco et al., 2005 and an undescribed specimen have been performed. The former comes from the Cuesta Lonsal site in Galve (Teruel) and it is late Kimmeridgian in age whereas the latter have been found in La PeÃuela site in Camarillas (Teruel) and it is Berriasian in age. The histological observations of the skeletal remains that were made from the thin sections in an optical microscope have allowed to determine the ontogenetic stage of the sauropods at the time of their death: Galvesaurus and the sauropod of La PeÃuela were adult and senile specimens, respectively. A mineralogical study of the paleohistological samples has also been carried out, combining optical and field emission scanning microscopy (FESEM). In the study it is observed that the diagenetic processes are similar in the bone remains of the two specimens. The apatite of the bones has not been modified during diagenesis. The fillings in vascular channels and cavities are mainly calcite cements, detrital grains and oxides. The fact that the observed processes are similar in the two individuals is probably due to the lithological similarity and the geological history of the formations in which the specimens were collected.
